The mixed-mode fracture of polycarbonate (PC)/acrylonitrile–butadiene–styrene (ABS) alloy is experimentally investigated in thiswork. The essential work of fracture method is employed to measure the mixed-mode fracture toughness of PC/ABS alloy. Results showthat the essential fracture work we increases significantly with the decrease in loading angles. Crack initiation angles are measured on thefractured specimens. The deviation of crack growth direction from the initial crack plane also increases with the decrease in loading angles,which corresponds to the increase of shear components. Microfracture processes of PC/ABS alloy with different loading angles areexamined in situ by a scanning electron microscope. Crazing structures are clearly seen around the crack tip. The appearance, growth,and coalescence of crazes can be observed in the microfracture processes, and the macrocrack propagation direction is finally determinedby the coalesced direction of crazes.
